O
One-touch Intercom Calling button
See Intercom Calling button.
Outside call
A call made from outside the Centrex system to an
extension within the Centrex system, or from inside
the Centrex system to a number outside the Centrex
system. If your Centrex system uses a dial-out code
(usually a “9”), you must dial it before you dial an
outside telephone number.
P
Premises equipment
The AT&T equipment controller and MLS- and
MLC-model telephones that you purchased as part
of your system, plus all other telecommunications
devices that are connected to your equipment
controller. For purposes of this guide, premises
equipment does not include any equipment that
connects directly to Centrex lines without going
through the equipment controller. See also System
and Centrex system.
Primary carrier
The required component of the AT&T equipment
controller that contains the primary processor
module and up to two 206 modules and two 400
modules. The primary carrier provides for
connection of up to 12 lines and 12 extensions. See
also Expansion carrier.
Primary line
The main Centrex line assigned to an extension,
generally used to place and receive all calls for that
extension. When a caller dials a phone number, the
call rings immediately at the extension where the
line is assigned as a primary line (unless line ringing
is changed to let another extension screen calls on
the line). See also Secondary line and Primary line
button.
Primary line button
The bottom leftmost line button on an MLS- or
MLC-model phone. See also Primary line.
Primary processor module
This AT&T module, which is always installed in the
center slot of the primary carrier, manages the
components of your premises equipment. See also
Expansion processor module.
Primary programming extension
The main extension from which you program
premises equipment, using the phone connected to
extension jack 10 on your equipment controller. See
also Backup programming extension.
Programmable button
A telephone button that can be set up to access a
feature. On MLS- and MLC-model phones,
programmable buttons can be used as Auto Dial
buttons (for one-touch dialing of Centrex feature
codes or telephone numbers) or equipment feature
buttons.
Proprietary device
A telephone or other device that is designed to work
with a specific system, and requires a special
interface to connect to the public telephone
network. For example, MLS- and MLC-model
telephones are proprietary devices that can only be
used with the equipment controller described in this
guide. See also Industry-standard device.
R
Recall
An equipment feature that sends a timed
switchhook flash to let you access a Centrex
service. (Use Recall only on an outside or inside
call; using Recall on an intercom call disconnects
the call.)
Ringer Equivalence Number (REN)
A measure of the power it takes to ring a phone or
other telecommunications device, usually shown on
a label on the bottom of the device.
S
Secondary line
A line assigned to an extension for call coverage
purposes, generally with delayed or no ringing.
When a call comes in on the line, it rings first at the
extension where it is assigned as the primary line;
only if there is no answer does it ring at the
extension where it is a secondary line. See also
Primary line.
SMDR (Station Message Detail Recoding)
See Call reporting.
Speed dialing
A feature that lets a user dial a telephone number
quickly by dialing a short code.
